I’m trying to figure out which corn snake sex is the longest females or males. I know ball pythons the females are the larger but I’ve read that with corn snakes, It’s the male and now I’m reading other places where it says it’s the female, I don’t know who to believe.

I don’t know, what I’ve seen is females get bigger. But I can tag people that own a lot of corn snakes. @noodlehaus @caryl

Neither, if you don’t breed them. Not sure how many corns I’ve had over the years but it’s in the hundreds. Females’ bodies obviously experience a toll when producing eggs which the males’ do not. That effect is very minor in the long run if care for them well. I do find joy in producing babies, but they’re primarily fascinating pets for me. I very rarely breed a female two years in a row, and a fair portion of my collection consists of snakey senior citizens and other who will not ever be bred.
Their size basically a function of their individual genetics and the care they’re given. They do keep growing throughout their lives (AKA indeterminate growth) although their growth rate slows noticeably after the first 4 or 5 years, again depending upon the individual 's genetics.

Not always~
I have a male who is longer than any of my females and weighs around 2200. He’s lean. I sold a different male recently who I also kept on the lean side but still ran a good 1700. Bigger than most of my gals.
It’s uncommon, for sure. But still not entirely impossible.
I also have a female who just has not grown much. At 5 years she still weighs in at 1000g on a good day.

I haven’t noticed any significant difference between the adult sizes of either sex of corn snakes. I do notice that certain localities (and the morphs derived from them) can sometimes skew one way or the other. Okeetee corns often are pretty large. Keys and cinder tend to be more slender, although they can still be pretty long.

I honestly wouldn’t rely on the variable of size for the sex of the snake. Its something that can vary greatly depending on genetics, diet, general care or honestly sometimes it can be random.
Not a Cornsnake breeder or keeper but I’ve seen this too often in other snakes to not solely rely on size. Not all Ball Python males are smaller than females for example, I’ve seen some monster-size 3000+ gram male BPs in my time that dwarf breeding females… some females never grow larger than 1500 grams.
With colubrids the common occurence is that females grow larger to compensate for breeding and egg production, Hognose snakes for example are like this. But with Kingsnakes sometimes the males can be significantly larger than females.

Accurate. Corn snakes are in the “makes no difference, it’s individual rather than sex-linked” category of colubrids’ size category.
